To all who-1n it may concern.-

Be it kno wn that we, EVERETT S. WOOD and J ONAS Nonrnnoncitizens of theUnited States, and residents of Hopedale, county of Forcester, State of Massachusetts, have invented an Improvement in Filling-ExhaustionIndicating Mechanism for Looms, of which the following description, in connection with the accom panying drawings, is a specification, like letters and figures on the drawings representing like parts.

This invention has for its object the production of novel filling-exhaustion-indicating mechanism for looms whereby a change in the operation of the loom is effected automatically when the running filling has become sub stantially exhausted or woven off toa predetermined extent. Such change in the operation of the loom may be automatic stoppage, or it may be the actuation of a suitable instrumentality to effect automatic replenishment of the running filling without loom-stoppage, one form of replenishing instrumentality being shown in United States patent to Northrop No. 529,9{L0, wherein the running shuttle is automatically provided with fresh filling while the loom continues in action.

Our present invention is illustrated herein inconnection with an automatic filling-replenishing loom of the before mentioned Northrop type.

In the practical embodiment of our present invention as herein illustrated and described the filling-exhaustion-indicating mechanism comprehends two movable members, one of which intermittingly impinges on and is moved by means within the shuttle until the running filling is exhausted to a predetermined, extent, the other member being then movable longitudinally on said first-named member, an actuator on the latter operatively positioned by or through such longitudinal movement, and means to immediately and positively lock the actuator in its operative position. The member which controls the operative positioning and the locking of the actuator is movable with relation to the other member only when the predetermined exhaustion of the filling permits and then by impingement on a vibrating part of the loom, such as the shuttle, and when the actuator is operatively positioned the movement of the member on inoperatively positioned;

which it is mounted effects the actuation of a ment into operative position, the actuation of the loom-controlling instrumentality is assured even should there be a temporary disengagement of the vibrating part of the loom and the member which is moved by impingement thereon. tures of our invention will be fully described in the subjoined specification and particularly pointed out in the following claims.

Figure 1 is a top plan view of a portion of the left-hand side of a loom with one embodiment of our invention applied thereto, the running shuttle being in position for cooperation with the filling-exhaustiondndicating mechanism on the forward beat of the lay. Fig. 2 is a left-hand side elevation of the mechanism shown in Fig. 1, a portion of the automatic filling-replenishing mechanism at the opposite side of the loom being shown. Fig. 3 is a rear elevation of the transmitter intermediate the feeling devices and the replenishing mechanism. Fig. .t is an inner side elevation, taken at the left of the line 4: 4:, Fig. 1, of the feeling devices and a portion of the transmitter and its controller. Fig. 5 is a greatly-enlarged top plan View, partly broken out, of the filling-impinging member or feeler, the parts mounted thereon, and, the stand or casing in which said member is yieldingly sustained. Fig. 6 is a longitudinal section thereof on the line 6 7, Fig. 5, all of the parts being shown in their normal relative positions, the actuator, to be referred to, being Fig. 7 is a similar view on said line 6 7, Fig. 5, but showingthe actuator in its operative position and the means for looking it therein just before the These and other novel feaactive stroke of the supporting member be- ICC 7 w (see dotted lines, Fig. 2,) and by the fortime of operation of the replenishing mech ward stroke of the weft-hammer the latch is pushed forward, acting through arm d to turn the rock-shaft d in the direction of arrow 200 to effect the operation of the replenishing mechanism, substantially as in the Northrop patent referred to. The latch,.wefthammer, rock-shaft, and intervening connections constitute controlling means for the loom and in the present instance govern the anism.

As is usual in so-called feeler-looms, the shuttle S is shown in Fig. 1 as having an opening 1 in its side wall to register with the usual opening 2 in the front wall 3 of the shuttle-box B when the shuttle is properly boxed therein. The notched holding-plate 4 for the shipper S (omitted in Fig. 2) is depressed at 5 and supports a vertically-adjustable bracket 6, having an inclined top 7, on which is adjustably secured by screws 8 a casing or feeler-stand 9 10, substantially as in our United'States Patent No. 789,472, dated May 9, 1905, the inclination of the stand enabling the feeler to move in a path closely coincident with the path of the swinging lay A for the reasons set forth in said patent. The two parts of the stand are chambered out internally to receive the front end of the feeler, which forms one member of the filling-exhaustion-indicating mechanism, said member being shown herein as a flat elongated metallic plate 12, laterally enlarged at its rear end to form a head 13 and having a transverse portion 11 to slide freely within the chambered stand. A preferably cylindrical shank 14 extends forward from the enlargement 11 and slides freely through an opening in the front of the stand, a spring 15, coiled around the shank, (see Figs. 5 and 6,) moving the feeler member rearward into the position shown in said figures, shoulders on the stand limiting such movement by cooperation with the enlargement 11. The flat body 12 is slidably supported and guided in the opening 16 in the rear end of the stand, and the bottom of the opening is longitudinally and centrally deepened, as at 17, Figs. 6 to 8, leaving a shoulder 17* at-its forward end, to 'beagain referred to.

An upright transverse bearing 18 is rigidly secured to or forms part of the member 12 adjacent its head 13 to slidably support a shuttle-bunting or shuttle-actuated member 19, parallel to the feeler member and movable with it and also longitudinally relatively thereto. said member 19 ha ing its rear end inter nally threaded to receive the threaded shank 20 of a hunter 21, thus adjustably held in position and secured in adjusted position by a suitable check-nut 22.

From the bearing 18 forward to the enlargement 11 the flat body 12 is shown as centrally and longitudinally slotted at 23 to receive the long arm or extension 24 of a lever-like device or bell-crank fulcrumed on the body 12 by a transverse pin 26, the short arm 25 of said device being upturned and recessed at 27 to receive loosely the front end of the member 19. A cross-pin 19 on the latter enters elongated slots 28 in the sides of the recess27, so that sliding movement of the member 19 in its bearing in parallelism with the feeler member will rock the bell-crank on its fulcrum 26. Owing to the difl'erence in the length of the lever-arms 24 and 25, a very slight longitudinal movement of the member 19 will impart a greatly-amplified movement to the extremity of the arm 24:, such extremity being enlarged, as at 29, Figs. 6, 7, and 8.

We have herein provided the feeler member with upturned parallel cars 30 at the front end of the slot 23 and projecting freely through an elongated opening 9 in the top member 9 of the stand, and between the ears an actuator is fulcrumed at 31, the fulcrum-pin being extended beyond one ear to receive a coiled spring 32, one end thereof being held against the front of the ear and its free end 33 crossing the actuator and when at rest bearing against a shoulder 3O on the ear adjacent the sprin The actuator 34 is made as a flat plate having a downturned hook 35 and projecting above the rear end of the stand, the actuator projecting toward the rear of the loom, and above the fulcrum 31 the actuator is upturned at 36 to be engaged by the end 33 of the spring. The latter is so wound that normally the actuator is held elevated (see Fig. 6) in inoperative position. A depending extension or foot 37 of the actuator is carried down between the ears 30 into the stand and through the feeler-slot 23, the rear edge of the foot being shaped to present a toe 38 and a cam-face below it, said cam-face having a curved operating portion 39 and a substantially flat locking portion 40 below. The toe lies above the enlargement 29 on the lever extension or arm 24:, and the cam part depends in front of such enlargement, the relative position of the parts under normal conditions being shown in Fig. 6, and at such time the extension 24. is elevated and the hunter member 19 is in its rearmost position relatively to the feeler. The enlargement 29 is so shaped as to lie normally in the crotch between the toe 38 and the operating portion 39 of the cam-face, and when so positioned the member 19, bell-crank 24: 25, and actuator 34 all move in unison with the feeler proper and are relatively immovable. This IIO relative quiescence of the parts continues so 7 moving the feeler forward, compressing the spring 15, before the shuttle-wall can impinge upon the bunter 21 on the member 19, so that there will be no relative movement of the connected feeler members 12 and 19, the" beat up and through the aperture 1 in the shuttle-wall on each alternate beat up of the lay. When, however, substantial exhaustion of the filling in the shuttle permits the feeler to enter the shuttle a predetermined distance,

the diminution of the yarn mass will then be great enough to permit impingement of the bunter 21 upon the shuttle-wall before the feeler-head engages the filling, whereupon the member 19 will be moved forward in its bearing 18 parallel to the feeler before the active or forward stroke of the feeler begins. Such movement of the shuttle-actuated member immediately rocks the lever-like device 24 25, and the arm 24B is depressed from the position shown in Fig. 6 to that shown in Fig. 7, the enlargement 29 Wiping over. the operating portion 39 of the cam-face on the actuator-foot and moving the actuator 34: into operative position, the completion of such movement of the enlargement 29 carrying it from the cam portion 39 to the locking portion 4:0, (see Fig. 7,) locking the actuator positively in its ope'rative position. At such time the enlargement 29 is brought to rest upon the bottom of the recess 17 just at the top of the shoulder 17 and the active stroke of the feeler now begins by virtue of the force transmitted through the shuttle-wall to the member 19 and operativeL'v-connected parts. Immediately the enlargement 29 passes beyond the shoulder 17 and the shuttle-pressure lowers the enlargement into the position shown in Fig. 8, positively locking the parts in such position during the remainder of the stroke, the extension 24 being then on dead-center, the actuator being locked by the continued cooperation of the enlargement'29 and the locking portion A0 of the cam. By thus pro viding for the locking of the actuator contemporaneously with its operative positioning and its retention in locked condition no change can take place in the relative position of said actuator should-the feele r device jump forwardand temporarily separate the shuttlewall and the bunter, and the mechanism must necessarily operate as designed. The move ment of the member 19 in parallelism with the feeler by pivotally connecting it with the lever like device obviates any tendency to preventthe proper movement of such member 19 when engaged by the shuttle-wall. WVere such member rigidly connected with the leverlike device, the bunter would slide upon the 'inbefore described.

shuttle-wall when the said lever-like device turned or rocked on its fulcrum, and the friction between the shuttle-wall and bunter would be so great as to delay or altogether prevent the movement of the lever-like device, thus interfering with the proper'operation of the feeler device. This is particularly true should the bunter wear into the shuttlewall at all or if the wall should have a depression or unevenness of surface of any kind at the point of contact. With the construction shown there cannot be any movement of the bunter along the shuttle-wall, and hence the trouble before mentioned is absolutely and completely obviated.

By making the lever-like device light in weight and locating its fulcrum 26 very close to the center of gravity thereof and within the path of movement of the feeler 12 there is practically no tendency to move said device by momentum, and a very light spring 32 is amply sufficient to retain the parts in normal position and to return them thereto after relative movement of the feeler members hereficient filling in the shuttle to impart movement to the feeler proper by impingement thereon the actuator and the other parts mounted on the feeler remain relatively quiescent, the actuator being inoperatively positioned and so held, and consequently no change in the operation of the loom can be effected until just the desired point of exhaustion of filling is attained. Adjustment of the bunter regulates with great accuracy and closeness the quantity of filling remaining at such time, the indicating mechanism being also adjusted thereby for bobbin diameter and width of shuttle;

lVIeans for eflecting'a change in the operation of the loom by or through forward move ment of the operatively-posi'tioned actuator will now be described.

A transmitter 41 is fulcrumed on a stud 4:2 substantially parallel to the path of movement of the feeler, the inner end of the transmitter extending beneath the latch 0K and normally sustaining it in inoperative position, and at its opposite outer end the transmitter is bent laterally to form an upright ear 43 (see Figs. 1, 2, and 4c) and having a cam-slot 14:, substantially as in our patent hereinbefore referred to. A controller for the transmitter is arranged in positive andsliding connection therewith and is shown as an arm 45, fulcrumed on an' upright stud 46 on abracket 4:7, rigidly supported on the holding-plate 1, the free end of the controller passing through the cam-slotL L and across the top of the feelerstand. The extremity 48 of the controller passes under the actuator 34, and it is below the normal path of movement of the hook 35 thereof, as in Fig. 6, and preferably both hook and rear edge of the foot are slightly beveled to secure a firm contact when in operative engagement, as in Fig. 8. A spring So. long as there is suf- 49 normally holds the controller-foot in the low or inner end of the cam-slot 44, as shown in Fig. 4, and movement of the controller to the high or outer end of such slot will manifestly depress the adjacent end of the transmitter, rocking the latter on its fulcrum 42 and moving the latch (i into position to be engaged by the Weft-hammer W, as hereinbefore explained. So long as the actuator 34 is inoperatively positioned the reciprocation of the feeler device will move said actuator back and forth above the controller-foot and no co operation therewith can take place. When, however, the exhaustion of filling reaches'the desired point, the actuator is operatively positioned and instantly locked, as has been described, and then the foot 48 will be directly in the path of the hook 35, as shown in Fig. 7, before the active stroke of the feeler has begun. Consequently as the active stroke is effected by the forward movement of the lay the actuator and controller positively cooperate and the free end of the controller is moved forward as the stroke of the feeler is completed. Thereby the transmitter is rocked on itsfulcrum, the controller moving from the inner toward the outer end of the cam-slot 44, and the operation of the controlling means or instrumentality for the loom will be effected. The locking of the actuator not only insures the actuation of the desired instrumentality, as described, but it also serves to hold down the free end or foot 48 of the controller as the latter is moved outward, obviating the necessity of a fixed guard. therefor. After the active stroke of the feeler the spring 15 eflects the return stroke as the lay swings back, and

as the enlargement 29 engages the shoulder 17, which is slightly inclined, as shown, it is thrown above the position shown in Fi 7 and returned to the control of the spring 32, so that the latter restores the actuator to inoperative position and resets the member 19 as the shuttle-wall recedes from the bunter.

The sliding positive connection between the transmitter and the controller is not broadly claimed herein; but it is illustrated in connection with the novel portions of our present invention as an efiicient and desirable mechanism for use in connection therewith.

Various changes or modifications may be made by those skilled in the art without departing from the spirit and scope of our invention, one practical and efiicient embodiment whereof is herein shown and described.
